To ail whont it may concern:

Be it known that L Coonrnnr HYDE, a i

citizen of the United States of America, and a resident of the boroughof Manhattan, city of New York, and State of New York, have inventedcertain new and useful Improvements in Machines for Manufacturing Hoseor Tubes, of which the following is a specification.

This invention relates to machines for manufacturin hose or tubes, andparticularly conduits for electric wires.

While the principles of the construction of the machine are particularlyadapted to manufacturing conduits for electric wires, they are alsoapplicable to machines for manufacturing all tubes and pipes whichcontain an inner longitudinal lining, on which is a reinforcing-windingof a filamentary body and like pitch, which will harden when cold ordry, and the use of the machine is therefore not limited to anyparticular class of tubing.

Essentially it consists, first, in the combination, in a machine formanufacturing tubes on a mandrel on which the inner lining is formed andmeans for coating the inner por tion of the lining with talcum or othersuitsubstance, so that the plastic coating substance Will not stick theining to the material; second, in a machine coating with said plasticwaterproof coatin a machine of the kind described of means for windingon the reinforcing-windings; fourth, in a machine of the kind dcscribedof a device for drawing the completed the linin tube alon as it isformed" fifth in the co1nbig 7 I nation of said coating, winding, anddrawing devices with such other elements as are necessaryto reduce anoperatingcnachine for any given Kind of tubing.

he drawings which accompany the specification illustrate a machine whichis particularly adapted to the manufacture of conduits for electricwires,.such as are described inUnited States Letters Patent ho. 693,916,

dated li ebruary 25, 1902; but the .lllVGlltlOl'l is not limited tomachines for such specific purpose, and in a general way the machine isan improvement upon and a simplification of the machine described inUnited States Letters Patent No. 791,729 dated June t frames upoiReferring to the drawings, ure it is plan view of the machine. a is a lotudinal vertical sectional elevation of t 1e machine .on the line 2 2 ofFig. 1. 3 an elevation, partly perspective partly cross-sectional, onthe line 3 3 of Fig. 2, showing on a larger-scale certain details of the111achine hereinafter referred to. Fig. 4t is part perspective and partsectional View of the former and adjacent parts of the mandrel, showingthesmear-p0t and heater and indicating three of the winders. Fig. 5 is aper speetive View of one of the windingguides through which theWinding-cords pass.

Similar numbers of reference refer to similar parts throughout theseveral views.

The construction. of the best understood by a description of itsoperation.

Referring more especially to Fig. 2, 30 is a drum mounted upon thestandards 28, secured to the frame and standards of the H19; chine 1, 2,and 3. The drum 30 has wound upon it a strip of canvas 29 or othersuitable flexible material, which forms the inner longitudinal lining"of the conduit 14 This canvas strip has been previously cut to properwidth. This strip drawn under a perforated drum 30, containing talcumpowder, soapstone, or other nou-frict' .ial substance, whereby itreceives a coa'tii'ig of such powder on its inner surface. The strip 29is then drawn over the mandrel 24 through the former or thimble 22*, andthence over the reainer 24, the inner end of which extends through thesmear-pot 22 containing the melted pitch or other waterproofingcompound. The waterproofing preparaticui is kept melted in thenieltings'iot 1 36 by the heating device 25, which may be a gas heateror any other sui able heater and is admitted to the smear it 22 by thehandvalve 27'. In this sure i pot 22 the circular canvas tube is coatedwith the water;n'ooiing preparation and passes thence over the reamer24:, which, as shown haslongitudinal corrugations upon it (losi ned toi'ieutraliae the torsion produced by the winding-cords next to be desciUpon the hollow shaft 18 mountor drum in, desired) tour (more or less,if hilouuted in these ts .26 are the spools 2i,

machine will be r revolving cylinder upon which the cords 21 are wound.These cords pass over the ends of and are guided by the guides 18*, alsomounted upon the revolving cylinder or drum 18; 18 representssupplementary guides through which the cords 21 pass before reaching themain guides 18. The coated tube upon the corrugated reamer I 24 is woundby means of the Winders, just above described, with four (more or less)cords which are embeddedin the still soft exterior waterproof coating ofthe tube, and thus reinforce the strength of the tube at the same timethat they give it flexibilty. The

The revolving cylinder 18, carrying thewinding-guides, is revolved from the main shaft 4 by means of the gears15 and 16.

It will be understood that the gears driving the winding drum or reel 14and those driving the revolving cylinder 18 must be so propor- 'tionedin speed with regard to each other that the completed tube will not bedrawn through the machine by the winding drum or reel 14 faster than itis wound by the winding-guides upon the revolving cylinder 18with thecords 21. i

Referring to Fig. 4, it will be noted that the former 22 extends intothe smear-pot 22 to within a short distance of the rear wall of thesmear-pot. The object of this is that the edges of the canvas ribbonforming the inner tube lining are held together over the mandrel whilepassing' through the smear-pot, and the pitch or other Weather proofingcomound cannot pass through the crack or crevice to the inner side ofthe lining or onto the mandrel.

It will be seen that in my simplified machine I have done away with thenecessity of a supplementary winding to the canvas tube before itreaches the smear-pot. I have also made such changes in .the smear-potof the old machines as obviate this necessity, and,"

furthermore, no pickers or other feeding devices such as were used inthoold machines are necessary in mine. for the winding drum or reel whichdraws the tube through the machine takes the place of these feeding deofoperation by means of the hand-lever 4 vices. Such feeding devices wereobjectionable in that they marred the surface of the tube and also thatthey materiallyweakened its strength to such an extent that theysometimes brokethe winding-cord surrounding the tube. I have simplifiedthe old machines by rendering it unnecessary to use the cooling devicesIt will further be noticed that and hollow, mandrel necessary in them. I

cords, as were necessary in the old machines,

and this for the reason that my machinewinds the tube so close to thesmear-pot that the cords are embedded in the pitch while it is still 7soft, and, further, that by means of the pulling of the tube through themachine the windingcords are pulled'against the ends of thewinding-guides instead of away from them, as was the case in theformermachines, allowing the use of guiding slots instead of holes,thereby eliminating the time formerly taken to thread the cord throughthe holes.
